Motor with magnetic element to pair fan for generating induction power

Abstract

A motor with self power generation includes a motor body, at least one magnetic element, a shield case, an induction element, a transfer circuit board and a working module. The motor body includes a shaft member. The at least one magnetic element, located at the shaft member, is to generate a dynamic electromagnetic induction space while the shaft member rotates. The shield case, located close to the shaft member, is to shield the shaft member. The induction element, fixed at the shield case, has a portion located inside the dynamic electromagnetic induction space to generate an induction power while the shaft member rotates. The transfer circuit board has a transfer circuit electrically coupled with the induction element to receive the induction power to further generate a working power. The working module, electrically coupled with the transfer circuit, is to receive the working power to execute a default work.
